Does C# have streams?

@Quintec Streams are trash compared to what C# has

Which is System.LINQ

Im currently at the LINQ hotel in vegas

@Pavel LINQ is the best

@Pavel also using C# wouldn't allow me to make things like this to work

the language-integrated query part less so

You don't have to convert things to streams, LINQ operations work an anything with the IEnumerable interface

Which includes arrays and all collections

@dzaima Fixed: tio.run/##PY7BCoMwEETvfsUc46H9gHrSe6HQY@lhk6osRCPZWCjBb0/…

@dzaima magic

Streaming things really isn’t hard

@ASCII-only My solution is better

@Pavel extra typing extra typing

@Pavel :P

@dzaima I literally added a letter

but... yes that is a way better solution

@Pavel extra typing extra typing extra typing :p

@ASCII-only why does this work

@Quintec why not

matching on type

You can switch on type holy

@Quintec Because C#'s switch/case is actually a pattern-match like you might see in Haskell

well, a basic pattern-match for now at least

@ASCII-only oh thats cool lets get that added on my ever-growing infinite todo list

@Quintec You can switch on more than type, you can also do it on predicate, case foo when condition

Cool

can i see an example of linq

@Quintec Why don't you give an example of streams and I'll convert it

That might be the best way

@Pavel like so

@ASCII-only is that redundant though?

yeah

@Quintec Yes, but you can use any condition you want

It's just an example

just showing you can select a value in a when case as well

@ASCII-only ≔HCF«⎇κ▷HCF⟦κ﹪ικ⟧ι»⊞υ±¹ＦＥＮ×⁺²ι⁺³ιＦＥυ⟦ικ⟧⊞υ±÷Πκ▷HCFκ⎚ＩΣ∕¹✂υ¹

based on ⊞υ±¹ＦＥＮ×⁺²ι⁺³ιＦＥυ⟦κι⟧«Ｗ⊟κ⊞⊞Ｏκλ﹪§κ±²λ⊞υ±÷Π…κ²⊟κ»ＩΣ∕¹✂υ¹

On mobile so here’s some generic things

@ASCII-only oh that's very redundant

Sorry

@Quintec yeah about that in java, why couldn't there just be a forEach or map on the list object itself

@Pavel tio.run/…

@dzaima meh foreach loop is fine for me

@Quintec tio.run/##Sy7WTS7O/P8/sagosVLPLb/…

(or .ToArray() or whatever)

Map becomes select?

Yep

On the other hand, no mapToInt

Methods can be arguments? Hmm

LINQ

@ASCII-only wow that’s basically python

:P

It's called Query form LINQ

I prefer Standard form

oh god what did i just do

Darn why does C# have to be so appealing

@ASCII-only eh id prefer foo.filter(number -> number <= 3)

@ASCII-only can you put the select number part in front? Seems to read better that way

@Quintec C# has first-class functions, kinda. You can't assign/reassign methods, but you can assign/reassign function objects which are a bit different.

@dzaima foo.Where(number => number <= 3)

easy

oh cool

TIO

@ASCII-only lol that symmetry

still, that whole spam of capital starting letters i hate from C#

@dzaima I’m creating a new language called c#

@dzaima It gets worse in F# which uses javaCase for methods

@dzaima no need to follow that convention, but i guess that's unavoidable for things from the standard library

@Quintec this is a good idea

@Pavel uh what’s wrong with javaCase for methods

@Quintec i'm assuming it's because PascalCase for everything else

@Quintec Because most of the F# standard library is the .NET standard library, which is CSharpCase

methods look better in javaCase

oh

CamelCasd and mixedCamelCase lol

no that's PascalCase and camelCase

@Quintec that'd make C# ~2x more appealing to me :p

@dzaima same here honestly

@ASCII-only can i even make a program that does anything without having at least one method that starts with an uppercase letter? :p

@dzaima No, Main

@Pavel does C# have static blocks :P

@Quintec Yeah but it won't compile without a Main unless you mark it as a library which won't produce an executable but a dll

If you ignore the Main method you can link the F# library, which is hella weird to use in C# but technically you can make it work

Darn

@dzaima alternative name Cb

Also in C# they're static constructors

@Pavel what’s the C# equivalent of Swing

@Quintec Windows Forms

GTK# if you want it to play nicer with Mono, but Mono's winforms support is pretty good these days

@Neil wait but what does EvaluateVariable("HCF", k) do :/

@Pavel sadly still no WPF support

And there never will be

But Winforms is supposed to be open source and in .NET Core in 2019

huh

when you mess up shunting yard

oops

I finally got this thing to segfault instead of just not linking at all!

why is linking so hard

oh yeah @Neil :D

wait i can get rid of a few more

@dzaima wow, dzaima/APL is a thing now

@ASCII-only it's been for a while. almost long enough that i've gotten bored of developing it :p

@dzaima this is the situation with me and Charcoal :/

@ASCII-only but you were just talking about shunting yard implementing :|

@dzaima yeah, that was long overdue

like... a few months. at least

it's basically the only thing i've done to Charcoal all year

@ASCII-only dzaima/APL hasn't existed for a year :p

@dzaima well yeah but this has happened multiple times

wait

what

turns out i have pretty consistent commit rate???

do i have no life? probably

@dzaima nice 10/10
